21 Claims. (Cl. 232--15) This invention relates to covers for coin boxes or receptacles and more particularly to covers for coin receptacles of the type used in telephone coin collectors, such a receptacle being described,

for example, in United States Patent 1,121,063,`

issued December 15, 1914, to W. O. Beck.

An object of the invention is the prevention of fraudulent removal of the contents of coin receptacles.

Cash receptacles used in telephone coin collectors are ordinarily furnished with a hinged cover which has an opening therein through which the collected coins pass. A sliding shutter is usually provided for closing the coin receiving opening. A projection carried by an extension of the shutter is adapted to engage with a portion of the coin collector housing when the coin receptacle is placedltherein, this engagementY being eifective, when the receptacle is being inserted in the housing, to move the shutter to open position and being eifective, when the receptacle is being removed, to move the shutter to closed position. Means is ordinarily provided for automatically locking the shutter in closed' position.

In accordance with the usual practice the empty coin receptacles are prepared for distribution at a central cashiers ofi-ice. Before the cover is placed on the receptacle the locking means is set in free position, i. e., a position which allows the shutter to move to open position. The cover is now placed in position on the receptacle. The receptacles are then taken by designated employees to be placed in the coin collectors. As the receptacle is inserted in the housing the shutter is removed to open position as stated above and the locking means is ordinarily so arranged that just before the receptacle is fully inserted, the locking means is tripped and moved into locking position. Now when theV filled receptacle is later Withdrawn the shutter is closed as above mentioned, the locking means then being effective to hold'the shutter in closed position.

According to a feature of the present invention the locking means is so arranged that it isV protected against fraudulent operationby means of tools or otherwise.

In accordance with a specific embodiment of the invention the shutter locking means comprises a pawl mounted on the under side of the cover and operating in conjunction with teeth provided on an 11p-turned edge of an extension of the `shutter plate. The pawl may be biased in either of two positions, locking or free, by a spring. When in locking position the pawl engages with the teeth and prevents moving the shutter to the open position. The arrangement contemplated by the invention is such that the pawl is adequately protected against fraudulent operation by tools inserted in any manner 5 through the openings in the cover.

In accordance with a modiiication of the invention automatically operating means are provided which serve to reset the locking pawl in free position as the cover is placed in closed position 10 on the associated coin receptacle.

A complete understanding of 4the operation of the receptacle cover contemplated by the invention and of the various `advantageous features thereof may be gained from consideration of the 15 following detailed description and the annexed drawings in which:

Fig. 17 is a plan view of a part of the shutter extension arm showing particularly the arrangement of the teeth and the tripping cam.

Referring now to the drawings and rst to Figs. 1 and 2, a coin receptacle cover 2| is shown which is provided with a coin receiving opening 22 and a pivoted shutter 23 for closing said opening. The shutter is rotatably mounted on pivot 24, a bowed spring 25 being provided for normally holding the shutter in closed position. Two extension arms 26 and 21 are provided on shutter 23, arm 26 being provided with an upturned edge on which are formed teeth 3| and 32 and projection 33. Arm 21 extends upwardly from the inside of the cover through slot 34 to the outside of the cover and then laterally beyond the edge vthereof as shown. A tripping cam 35 is also provided on extension arm 26.

shield for the shutter and the other mechanism of the cover. Embossed portions 31 and 38 Yon wall 36 provide clearance for the teeth and projection 33 and for projection 35, respectively, when the shutter is rotated.

A rectangular casing 4| is mounted on inner` ner and for a purpose to be described subsequently. An aperture is provided in the pawl, the purpose of which aperture will be subsequently described. One end of biasing spring 46 is attached to an end of pawl 42 while the other end is attached to casing 4|.'

While casing 4| is mounted on inner wall 36, end portions of the casing extend, as clearly shown in Fig. 2, to the outer wall 39 of the cover. Further, the side walls of the casing extend beneath inner wall 36, grooves 41 and 48 (Fig. 2) providing clearance for projection 35and for the teeth and projection 33, respectively. It will be apparent from the above that the pawl is almost completely enclosed and is adequately protected against fraudulentV operation by the arrangement of casing 4I and the cooperating walls of the cover. No space is provided, for example, for entry of a tool which might be inserted through coin leveling hole 49'or through coin receiving opening 22 in an attempt to move the end of the pawl out of its locking engagement with the teeth on arm 26.

Referring now to Fig. 3, the manner in which shutter 23 is moved to open position, as the coin receptacle is inserted in the coin collector housing, is illustrated. A portion 5| of the guiderail, which is attached to the coin collector housing is shown, the guide-rail being provided, as shown, with an aperture 52 in which the end of arm 21 is positioned when the coin receptacle is An inner wall 36 is fastened to the inside of the cover, acting as a protectingl placed in the housing. Then, as the receptacle is pushed back into position in the housing in the direction indicated by the arrow, arm 21 is prevented from moving by the contact with the edge of aperture 52 so that the shutter is, in effect, moved to open position with respect to coinreceiving opening 22. Conversely, of course, when the receptacle is being moved in the opposite direction, that is, when it is being withdrawn from the housing, the shutter, is, in effect, moved to closed position with respect to opening 22. The respective dimensions and arrangement of the coin receptacle and the receptacle housing are such that it is impossible to insert the receptacle in the housing without rst positioning arm 21 in aperture 52.

Before the receptacle is inserted in the housing, locking pawl 42 should be set in free position to allow shutter 23 to open. The pawl is shown in locking position in Fig. 2, one end of f the pawl being in locking engagement with the edge of tooth 3|. In order to move the pawl to free position, a suitable tool is inserted through aperture 55 (Fig. 4) provided in one of the side Walls of casing 4| (this action taking place, of course, before the cover has been placed on the coin receptacle) and the pawl is rotated or tipped to the position shown in Fig. 4. Spring 46 acts to bias the pawl in whichever direction it may be rotated beyond the dead center position; the effective action of the spring in each position (Figs. 4, 5, and 6) being indicated by the respective arrows.

It will be noticed that in the position of Fig. 4, the pawl is free of the teeth carried on arm 26 and does not therefore interfere with the movement of the shutter. Projection 44 of the pawl is in Contact with the opposite edge of arm 26, that is, the edge opposite to the teeth.

The pawl having been set in free position, the cover is placed on the coin receptacle and sealed after which the receptacle may be inserted in the coin collector. Now, as stated above, the shutter is opened as the receptacle is inserted in the housing (Fig. 3) until, when just short of the fully opened position (the approximate position illustrated in Fig. 3), projection 35 is brought into contact with projection 44 of the pawl and as the relative movement of the receptacle and the shutter continues, pawl 42 is rotated about pivot 43 by the camming action of projection 35 until the position shown in Fig. 5 is reached wherein, as shown, the opposite end of the pawl is in Contact with projection 33. As indicated by the arrow, the biasing action of spring 46 is now in a direction opposite to that of Fig. 4. (The end of spring 46 is attached to pawl 42 at a point slightly below the horizontal center line so that the effective direction of the biasing action is as illustrated even though the pawl is approximately horizontal.)

The pawl remains in the position shown in Fig. 5 until the coin receptacle is removed from the coin collector housing. As the receptacle is being removed, shutter 23 is, in the manner previously described, moved to closed position with respect to coin opening 22. As the shutter moves in this direction, projection 33 is moved out of Contact with the end of pawl 42, whereupon the pawl, due to the biasing action of spring 46, moves to the locking position shown in Fig. 6. As the shutter closes, the pawl rides up the inclined edges of teeth 3| and 32, dropping down back of the straight edge of each tooth as said tooth passes from kunder the pawl. During the closing motion of the shutter vthree definite locking points are provided, therefore, one` as the pawl drops back of projection 33, another as it drops back of tooth 32and a third (shown in Figs. 1 and 6) as it drops back of tooth 3|,this Vlast position corresponding to the fully closed position of the shutter.

After the coin receptacle has been removed from the coin collector, the seal is broken by an authorized person and the cover removed from the receptacle. Before replacing the cover, the pawl is set infree position as before.

Referring now to Figs. 7 to 10, a modication of the invention is illustrated in accordance with i which an automatic resetting mechanism for the locking pawl is provided. It will be remembered that in accordance with the-arrangement just de` scribed, pawl 42was manually set in free position by means of a suitable tool. n accordance with the present modification, however, the pawl is automaticallyV set in free position as the cover is placed in position on the coin receptacle.

Referring krst to Fig. 7, a coin receptacle cover 6| is shown being placed in position on coin receptacle 62. Cover 6l is, in general, similar to cover 2| previously described, being provided with an inner plate 63 and an outer plate 64 (Fig. 8) upon which plates is mounted a pawl casing 61. A pawl 68 (Fig. 9) is mounted within casing 61 and operates in a similar manner to vthat previously described in reference-to pawl 42. Pawl 661s, in fact, similar to pawl 42 the only essential diierence being that, in the instance of pawl 68, an aperture 1| is provided therein. As shown in Fig. 9 an aperture is provided in one of the side walls of casing 61, an edge 12 of the aperture being beveled. VAn arm 13 is mounted on the side of casing 61 being rotatablysupported on lug 14 (Fig. 9). The free end of arm 13 passes through slot 15 which is provided in one of the end walls of casing 61. A plunger 16 is positioned in sleeve 11, which is provided on arm 13, a spring 18 serving to bias plunger 16 in the direction of the pawl casing. A second spring 8| is associated with arm 13, one end of the spring being anchored in notch 82 (Fig. 9) and the other end passing through aperture 83, provided in lug 14, `and resting against sleeve 11 as shown in Figs. 8 and 16. The lspring acts to normally hold arm 13 in the position shown in Fig. 8.

Cover 6| is, like cover 2| previously described, provided with a coin receiving opening and a shutter; of similar arrangement and operating in a similar manner to that of shutter 23, for closing said opening. An extension 89 (Fig. 8) of the shutter Which is similar in form to extension 26 previously described, is provided with a. tripping `cam and two teeth and a projection (one tooth 86 being shown) which are similar, respectively, to tripping cam 35, teeth 3| and 32 and projection 33 previously described. A spring (not shown) acts in a manner similar to that of spring 46 previously described to bias pawl 68 either in locking or free position. Y

Assuming. now, in order to illustrate the operation of the automatic resetting mechanism, that pawl 6B is in locking position and that cover 6| is about to be placed inposition on receptacle 62. Arm 13 is held in the position shown in Fig. 8 by the action of springl and tip 81 (Fig. 9) of plunger 16 is positioned in aperture 1| of pawl 66, spring 18 acting, as pointed out above, to force plunger 16 towards pawl 68.

Now,.as cover 6| is closed, the free end of, arm 13 is broughtj into contact with projection 9| provided on an end wall of the receptacle (Fig. 7)

' which Contact causes, in effect, movement of arm 13 about lug 14 in a direction approaching wall 63. As arm 13 is moved in this direction, pawl 68 is rotated in the same direction, due to the engagement of projection 81 in aperture 1|, until the pawl reaches its free position. Now as the movement of arm 13 continues, the edge of plunger 16 is brought into contact with beveled edge 12 which contact is effective to cam plunger 16 back against the action of spring 18 so that, as shown in Fig. 10, tip 81 is withdrawn from aperture 1| of pawl 63. Pawl 66, which is now in free position being biased and held therein by the action of the biasing spring previously referred to, is therefore released from any restraining force of the resetting mechanism and may be tripped into locking position as above described. (In view of the fact that pawl 68 is tripped into locking position during movement of the shutter to the open position in the sarnc manner as pawl 42 previously described it is not thought necessary to again describe this operation in detail.)

After receptacle 62 has been removed from the coin collector housing and as cover 6| is removed from the receptacle, arm 13, being freed from contact with projection 9 is returned by the action of spring 8| to the position shown in Fig. 8. As this position is reached, tip 81 again enters aperture 1| in locking pawl 63V (now in locking position) and the resetting mechanism is again in position to reset the pawl when the cover is subsequently placed in position on the coin receptacle and closed.

Referring now to Figs. 1l to 13, a modication of the automatic resetting mechanism just described isdisclosed. Here again we have a coin receptacle cover, similar to cover 2| previously described, including an inner plate and an outer plate 96. As before, a coin receiving opening is provided in the cover with a shutter, similar to shutter 23, for closing the opening. An eX- tension 91 ofthe shutter (Fig. l1) corresponds to extension 26 of'shut-ter 23 and is provided with a tripping cam 98 similar to cam 35, a projection similar to projection 33 and two teeth (one 99 being shown) similar to teeth 3| and 32.

A pawl casing ||l| is mounted on the cover, a locking pawl |92 (Fig. 13) being mounted within the casing. This pawl is similar, and functions similarly, to pawls 42 and 68 previously described and is, like pawl ,68, provided with an aperture |68, (corresponding to aperture 1|). The pawl is provided, as were pawls 42 and 68, with a spring (not shown) for biasing it in either the free or locking position. An arm |63 is mounted on the fside of casing 6| being rotatably supported on lug |66. The free end of arm |63 passes through slot |69 which is provided in one end wall of casing I0 A resetting pawl IEis rotatably mounted on lug |66 (Fig. 12) by pin |61 which is positioned in apertures and ||2. Tip ||3 of pawl |35 passes through aperture Iii in arm 63 and aperture I9 in the side of casing l 6 l. Spring |5 is associated Witharm |33, one end being anchored in slot |56 and the free end passing through aperture |1 of lug |64 and being positioned in aperture ||8 of resetting pawl |65. Spring ||5 acts to hold arm |63 in the position shown in Fig. 11 and also tends to rotate resetting pawl |05 in a direction to bring tip H3 into contact with looking pawl |92.

The operation of the mechanism is, in general, similar to that of the arrangement illustrated in Figs."7 to 10, the mechanism being in the position shown in Fig. 11 before the cover is placed in position on the 'cin receptacle. In the position of Fig. 11, tip I I3 of resetting pawl |05 is engaged with aperture |08 of locking pawl |02, spring ||5 acting, as previously mentioned, to so bias pawl` |05 that tip I I3 is urged towards locking pawl |02. Now, when the cover is closed, arm |03 is rotated in the manner previously described in reference to arm "I3, locking pawl |82 being rotated in the same direction due to the action of resetting pawl |95 until said locking pawl snaps into its free position. As movement of arm |03 continues, tip

. II3 is brought into contact with the edge of aperture H9, this contact being effective to so rotate resetting pawl |05 against the force of spring IE5 that tip H3 is, as shown in Fig. 13, withdrawn from aperture I 08 of locking pawl |02. Locking pawl |02 is therefore freed of any restraining force by the resetting mechanism.

In the manner before described, the resetting mechanism returns to the normal position (Fig. 11) when the cover is removed from the receptacle, tip ||3 of resetting pawl |05 thereupon reentering aperture |08 of locking pawl |02.

Referring now to Figs. 14 to 17, a modied form of the locking arrangement is disclosed. In accordance with the present modified form, locking pawl |2| is mounted vertically in pawl casing |22 Whereas, in the form rst described, locking pawl 42 was mounted horizontally in its casing. So far as the general arrangement of the cover and shutter and their operation is concerned, however, the present modiiication is similar to the embodiment previously described and illustrated so it is not considered necessary to again illustrate or describe in detail the features common to both forms.

In accordance with the modification, pawl |2| is rotatably supported on pivot |23 which is, in turn, supported by the side Walls of pawl casing |22. Casing |22 is mounted on inner plate |24 and outer plate I 25 of the cover in a manner similar to that in which casing 4| is mounted. Spring |25 is supported by the end walls of casing |22 and acts in conjunction with the tip of pawl |2| to bias said pawl in Whichever direction beyond the point of deadcenter itis moved. An aperture |3| is provided in one side of pawl casing |22 through which a suitable tool may be inserted to manipulate the pawl, the end of the tool being positioned for this purpose in aperture |32 of the pawl.

While as previously stated the operation and general arrangement of shutter |33 is similar to that of shutter 23 previously described, the arrangement of extension arm |34 (Fig. 17) differs somewhat from that of the corresponding part (extension arm 26) of the form rst described. Inthe present case, teeth |35, |36 and |31 are embossed on up-turned edge |4| of the shutter while tripping cam. |42 is embossed on up-turned edge |43.

The operation of the present locking arrangement is similar, in general, to thatl previously described. Let us assume, for example, that Vthe coin receptacle is being inserted in the coin collector housing, the cover being, of course, in

closed position and locking pawl I2| being set in free position as shown in Fig. 14. Shutter |33 is moved to open position as the receptacle is inserted in the housing in theY manner previously described, projection |42 (Fig. 17) being brought into engagement with the `edge of pawl I2I. As movement of the shutter continues, projection I 42, in passing pawl I2,|, causes rotation of said pawl against the action of spring |26, to .the locking` position shown in Fig. 15. As

shown in this figure pawl I2| rests in contact with up-turned edge |4| of extension I 34.

Now as the receptacle is subsequently removed from the housing, shutter |33 is moved to closed position in the manner previously described, pawl I2I riding over the sloping edges of teeth |35, |36 and |31 but remaining as shown in Fig. 16 (the arrows in Figs. 14, 15 and 16 indicating the biasing direction of spring |26) biased in the locking direction so that, as each successive tooth is passed, the pawl snaps behind the face thereof thereby providing three definite locked positions as in the instance of the form previously described. After the cover has been removed from the receptacle, pawl I2I may be reset in the free position of Fig. 14 by means of a tool of the nature previously referred to.

It will be understood that the general mounting arrangement of pawl casing |22 is similar to that previously described in reference to casing 4| so that the locking pawl in the present instance also is adequately protected against fraudulent manipulation. v
